Alex Vaghin	bc2ef10f1b	cpu: add gccgo implementation ... It uses __get_cpuid_count, provided by cpuid.h. The xgetbv is implemented after its counterpart in cpu_x86.s.

Tobias Klauser	538ab54ba9	cpu: introduce and export type CacheLinePad ... Add a CacheLinePad struct type that has a size of cacheLineSize. This can be used for padding structs in order to avoid false sharing.

Andreas Auernhammer	4adea008a5	cpu: new package ... This CL introduces a new cpu package for CPU/platform feature detection. The cpu package is basically a copy of `internal/cpu` of the standard library. Revision: bf86aec25972f3a100c3aa58a6abcbcc35bdea49 This CL does not export ARM64 and PPC64 feature detection since at the moment ARM64/PPC64 requires standard library support.
